IEONING MACHINE. i

Application led May 25, 1923. Serial No. 641,416.

To all' whom t may concern:

Be it lmown that I, LAWRENCE BURZYN- sul, a citizen of the United States of America, residing at Benton, in the county of 'l Franklin and State of Illinois, have invented kcertain new and useful Improvements 'in Ironing Machines, of which the following is a specification.

This invention relates to certain new and useful improvements in ironing machines and has particular reference to a motor operated reciprocable frame resiliently supporting an electrically heated iron above an ironing board.

The primary object of the invention embodies in an ironing machine of the above type, an ironing board having a rack frame reciprocably mounted thereabove with a' motor operating a gear and clutch devicesv associated with the rack frame to reciprocate the latter, the clutch devices being operable when the rack frame reaches yits limitvof movement in opposite directions for reversving the direction of movement of .the rack frame.

lThe invention further embodies a reciproeating carriage for an electrically heated or sadiron, with spring devices associated with the carriage and iron for normally holding the iron in an elevated position above an ironing board. Y

With the above general objects in view and others that will appear as the nature of the invention is'better understood, the same consists in the novel construction, combination Vand arrangement of parts hereinafter more fully described, illust-rated in the accompanying drawings, and pointed out in the appended claims. j

In the drawings forming a part of this application and in which like' designating characters refer to corresponding parts throughout the several viewsr-k Amachine constructed in accordance with'the the worm on the motor shaft forj operating Figure l is a top plan view of anironing operating f the U-shapedy straps, and `to maintain 'the gear train and the resilient mounting of the iron, Y r y Figure is a detail sectional view taken on line IIIe-III of Figurel showing thel gearing at one side of the machine for reciprocating the rack frame, i n

Figure 4 is a detail sectional view taken 60 on line lV-IV of Figure'l, v Y.

Figure 'is a fragmentary side elevational view'. of the machine, showing by dotted lines the train of gearing ofthe opposite side of the machine with lthe idlerv gear for reversing the direction of movement of the rack frame, l y Y '7" `Figure 6 is a detail sectional view take-n v on line Vl-VI of Figure l, Y I

Figure 7- is a cross sectional view taken 4on line VIL-VII of Figure l-showing the resilient mounting for the iron with the ironing boardv spaced below the same,

Figure 8 isa fragmentary side elevational view showing a bayonet slot construction for holding the iron in 'an-elevated position, l Referring more in detail to the accompany-` ing drawings, there is illustrated an ironing board l mounted upon hinged legs 2 that may be braced inV any suitablemanner, the legs preferably being folded to assume apo- .sition adjacentthe under side ofthe board 1 whenout of use.` To accommodate the reciprocal mounting of an iron above the board 1", the latter adjacent one end thereofis pro- 85 vided with side wallsl carrying forwardly directed guide. arms 4,l the upper edges of c the side walls 3 andv guide arms 4 being rabbetted with a series of antiLf-riction roller bearings 5 journaled in the rabbetted portion.

, kA. pair offrack bars 6 are longit'udimm7 slidable in the rabbetted portion of the side ,y l walls 3 and guidearms 4, the same'being connected attheir forward ends shown in Figures l, 2, and 7 by U-shaped-straps havf ing horizontalfcross arms 7 and vertical' y side legs 8, the legs 8 being slotted as at 9.to v slidably receive the inwardly directed pins 10, carried by the rack bars 6. As shown, an electrically heated iron 11k is securedto' the lower sides of the horizontal arms 7 of 'f iron 11 in an'elevated position with respect to the vironing board 1,'lateral brackets l2 105 are associated with Athe irontl 11 with springs v cross braces 34 and a clutch element 21a hav` 13 connecting the outer ends of the brackets 12 to the rack bars 6 at points outwardly of said straps as clearly shown in Figure 7, pressure upon the handle of the iron 11 in a. downward direction, lowering the iron against the tension of the springs 13, for engagement with au article placed upon the ironing board 1, as will at once be obvious.

To effect reciprocating movement of the rack bars, a motor and train of gearing driven thereby with clutch devices are associated with the rack bars 6, the motor 14 being mounted upon the ironing board 1 adjacent one end thereof between the side walls 3 and having a shaft 15 operating a werm gear 16. pair of standards 17 carried by the board 1 rotatably support a shaft 13 having a worm gear 19 fined thereto midway the ends, in engagement with the worm 16y as shown in Figures 1 and 4. Each endjof the shaft 18 has a gear 20 j ournaled thereon, a clutch element 21 being formed integral with the inner face of each of the gears 20. as shown more clearly in Figures 3, 4 and 5, side plates 22 and 23 are secured to the opposite side walls 3 and project upwardly of the rack bars 6, a shaft 24 being journaled in the upper ends of the side plates 22 and 23 and supporting upon each end thereof the fixed double gear having a toothed portion 25 meshing with the teeth of the adjacent rack bar6 and a smaller toothed portion 26 meshing with a gear 27 journaled in; a bracket 28,' the gear 27 being in mesh with the gear 2O upon the shaft 18. The reverse movement ofthe rack bar is effected by the interpositioning of an idler pinion 29 between the gears 20 and 26, the idler gear 29 beingV associated with the gear train adjacent the side plate 23.

The devices for effecting reciprocation of the rack bars 6 include pairs of standards 30 supported by the board 1 at opposite sides of the shafts 18 and 24 that slidably support at the upper ends thereof arms 31 and 32 having rollers 33 upon the oppositely projecting endsadjacent the rack bars 6, the arms 31 and 32 having fixed thereto 'and slidable therewith cross braces 34 showing more clearly in Figures 1 and 4. The shaft 13 rotatably vprojects through the beveled blocks 31a and 32aL for cooperation with Ithe sliding arms 31 and 32 respectively, shifting the arms and the clutch elements movable therewith for reversing the direction of movement of the rack. bars 6.

From the above detailed description of the device, it is believed that the construction andv operation thereof will at once be apparent, it being' noted that in connection with the iron 11, the same is of the electric type as illustrated and is resiliently supported upon the forward ends of the rack bars 6 normally to occupy a position elevated above the ironing board 1. When an article to be ironed has been placed upon the board, downward pressure of the handle of the iron will lowerthe same against the tension of the springs 13, and when pres'- sure is relieved thereon, the iron will be f5 automatically elevated to eliminate possibih ity of burning the article being ironed. The motor 14 operates the shaft 15 and worm 16 motion thereof being communicated by the worm gear 19 to the shaft 18 and tov the desired clutch element 21a. Assuming that the devices are coupled as illustrated in Figure 1,'the gear train positively drives the gear 25 adjacent the side plate 22 for shifting the iron 11 in a direction over the board 1 toward the motor 14, the beveled block 31a carried by the rack bar 6 at the proper time engaging the roller 33 to shift the arms 31 and 32 with the clutch elements 21a carried thereby and vplacing into positive operation the opposite gear 25 adjacentthe side plate 23, the interpositioning of the idler gear 29 as shown in Figuresl and 5 effecting the reverse reoiprocation of the rack bars 6. To relieve the strain upon the rack bar lwhile it is being positively shifted, a shaft 36 as shown in Figures 1 to 5 is journaled in thefrear ends of the side plates 22 and 23 and has fixed adjacent each end thereof a pinion 37 meshing with the teeth of the rack bars 6, providing for an even movement of the rac-k bars when only one rack bars 6, the idler gear 29 being provided to effect suoh reciprocation.

Another form of iron support is shown in Figure 8, the side legs 8a of the U-shaped brackets supporting the iron 11., having bayonet-shaped slots.v 9a formed therein to slidably receive the pins 10 carried by the rack bars 6. When it is desired to retain the iron 11 elevated with respect to the board 1, the iron is moved upwardly and then laterally shifted to position the pins 10 in the side the slots 9a.

While there are herein shown and described the preferred embodiment of the present invention, it is nevertheless to be portions of the lower ends of understood that minor cha ges may be made therein without departing from the spirit and scope of the invention as claimed.

I-Iaving thus described the invention,'what I claim as new is l. In an ironing machine of the typede` scribed, a board, rack. bars reciprocably mounted above the board, an iron resiliently supported by said rack bars and means for reciprocating ltherack bars, said reciprocating means including a motor,` a train vof gearing interposed between the motor and the rack bars, said gearing train including two sets of gears each set cooperating with a rack bar, a reversing gear associated with one ofthe gear sets, `and a clutch device operable to move into alternative engagement with one or the other of the sets of gears.
